ROTARY PUMP.

Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed February 21, 1906. Serial N 0.. 302,276.

T 0 all whom it may concern:

Be it known that I, JAMES JOSEPH ODoN- NELL, a citizen of the UnitedStates, residing at Paducah, in the county of McCracken and haveinvented a new and useful Rotary Pump, of which the following is aspecification.

This invention relates to centrifugal rotary pumps, and its object is toprovide a 3 simple and compact device of this character particularlydesigned for use in pumping out barges. I

Another object of the invention is to provlde a pump so constructed asto practically prevent all vibration of the parts during the operationof the pump, there being a sectional drive shaft and a sectional outletpipe used in connection with the pump, said sectional pipe carrying amotor for actuating the pump. 1

With these and other objects in view the invention consists of certainnovel features combinations of parts which will be hereinafter morefully described and pointed out in the claim.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings: Figure 1 is a diagram showing a number of barges orscows in tow, each of the severaL barges being equipped with a pump andall of sa1d pumps being provided "with flexible means whereby power maybe conveyed thereto from the tug boat. Fig. 2 is a vertical sectionalview of a pump in connection with the system. Fig. 3 is a horizontalsectional view taken on the line A-B, Fig. 2.

Referring to the figures by characters of reference, BB designate aplurality of barges or scows in tow of a tug boat T, said barges and tugboat being flexlbly connected in the usual or any referred manner so asto be capable of in epen'dent movement laterally one another. barges isprovided with a pump designed to be actuated'by power generated upon thetug boat T. In the present instance a .dy-

namo D has been indicated upon the tug boat and the same has been shownconnected by means of wires with a'motor M located upon each barge orscow, there being switches S provided for placing any one or more of themotors in circuit. Although in Fig. 1 nfechanism has been shown forelectrically operating motors it is to be understood that, if

Each of the preferred, other means may be utilized in lieu thereof.

Each pump which is used in connection with the system consistspreferably of a casing 1 of approximately elliptical shape in verticalsection, open at the bottom and having a depending flange 2 with which acover plate 3 is detachably connected. Said cover plate and the lowerpart of the casing is encompassed by a strainer 4 having a flange 5 forthe passage of securing members, such as machine screws 6, whereby thestrainer is detachably connected with the casing.

' The upper part of the casing has a bearing 7 for the passage of ashaft'S carrying the pump head H. The latter may be described asconsisting of two concavo-convex disks 9 and 10 connected together andspaced apart by a plurality of substantially radial wings 11, the hollowor concave sides of the disk being opposed to each other, and the edgesof the disks, which taper in the direction of each other, being spacedsuitably a circumferential outlet 12. The bottom disk 10 has an inlet 13surrounded by a flange or collar 14, which is concentric with the axisof the shaft 8, and which has a bearing in the plate 3.

The casing 1 is larger than the pump head H both diametrically andaxially which being filled with water when the pump is in operationserves in a measure as a reservoirto produce a steady outflow at the endof the delivery pipe. The casing has also an outlet which is disposed toone side of the shaft 8 and with which is connected an exit pipe 15extending upwardly and terminating in a spout 16. The exit pipe isprovided with brackets 17 affording additional bearings for the shaft 8.It will be found convenient to form the exit pipe with a lateral offset18 to afford room for an electric motor M of ordiapart to provide naryconstruction, which is connected with 1 the shaft 8, and the casing ofwhich, 19 may be connected with the pipe 15, so as to be supportedby'the latter.

The shaft 8 and the exit pipe 15 may each be composed of a plurality ofsections connected together by suitablejoints or coupliipgs, as 8' and15, for convenience in han- If it shall not be desired to equip eachbarge with a pump, the wiring may still be maintained, and a pump may becarried from one barge to another and the motor may then be connectedup, as will be readily understood.

The improved pump of the present invention is very simple inconstruction and effective in operation, Beingia submerged pump,

it will operate effectively to drain the water from the hold, and leakswill not interfere with the operativeness of the device.

Having thus described the invention, What is claimed is Z- v A pumpcomprising an inverted b0Wl-like casing) having an open bottom, a caplate detac ably secured across the open ottom of the casing andhaving'a central orifice superposed fixedly disposed frusto-conica diskswithin and spaced throughout their extent from the wall of the casing,radial wings between and integral with the disks, the inner ends of saidwings being cut away, there being a continuous annular outlet openingbetween the peripheral portions of the disks, a tubular casing u I ing areduced en projecting into the orifice in the cap plate, sald extensionbearing upon the cap plate, an outlet pips extending from the top of thecasing, a sha journale'd thereon and secured to the up er disk, aremovable pipe section upon t e first mentioned pipe, a shaft sectionjournaled thereon and detachably engaging the first mentioned shaftsection, and a motor mounted upon the removable pipe section for drivingthe shaft.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
